SUSv3 alignment - most of this work was done for 2.0/2.0.1.

The Realtime, Advanced Realtime and Tracing option groups are also not implmented. Need an analysis / decision on the missing features to either decide when to add, or to document why we don't want to add them. Omitting an Option group doesn't necessarily require an explanation, but it would be good for people coming fresh to the LSB to be able to understand the issues on those as well.
